Contact Angle analysis is used to measure the forces that affect the interaction of solids and liquids and can provide valuable information about surface and coating properties to help optimize coatability and adhesion. This technique is frequently used to study wettability of surfaces by different coatings, to investigate hydrophobicity/hydrophilicity of materials, to determine optimum surfactant levels, and to characterize the adhesion of coatings to different substrates. Microbalance-based dynamic contact angle (DCA) analysis provides a comprehensive scan of a large surface, minimizing errors arising from localized surface contamination and other sample inhomogeneity. Video-based optical contact angle (OCA) analysis provides analysis of non-uniform surfaces including production specimens and other "real world" samples.

  • Contact Angle Analysis (wettability, surface energy, homogeneity and topography of a solid sheet or thin film) - paints and coatings, reinforced composites.
  • Wilhelmy Plate Tensiometry (surface and interfacial tension of a single or multi-phase formulation) - paints and coatings.
  • Wicking Rate (absorption kinetics of aqueous solutions into porous materials) - paper, film and ink products, pharmaceuticals, textiles.
  • Critical Micelle Concentration (effectiveness and efficiency of surfactant adsorption in solution) - detergents, pharmaceuticals, paints, inks, and coatings.
  • Pendant Drop Surface and Lamella Surface Tension Measurement.
  • Temperature / Environment experiments are possible using a Peltier chamber (-20° - 150°C).
